SPECIFICATION forming part of Letters Patent No. 773,417, dated October 25, 1904.

7 Application filed November 10, 1902 Serial No. 130,791. (No model.)

To (l/ZZ whom it may concern.-

Be it known that I, ARNO PoHoRznLEoK, a subject of the King of Saxony, residing at 1 Alte Oschatzerstrasse, Oschatz, in the Kingdom of Saxony and Empire of Germany, have invented new and useful im provements in Machines for Making Wickerwork, of which the following is a specification.

My invention relates to machines for making wickerwork.

It has been proposed to make wickerwork by alternately bending backward and forward the required straight elements or stakes, somewhat in the manner of the warp-threads in a loom, so that after each such change the flexible elements or withes can be laid in and pushed down between them, so as to'form the wickerwork. The change in the position of the first-named stakes was effected in such method by means of cords having eyes or loops through which the stakes were passed and by means of which they were bent backward and forward. 7

According to the present invention for the cords provided with eyes or loops spring-teeth or grippers or properly-shaped springs arranged in rows are substituted, which by their working bend the stakes from their normal position, and so form the shed in which the withes can be laid and pressed down.

The arrangement in the method of construction now to be described is especially applicable to the making of basket bottomsand angular basketsfor example, traveling-hampersand some modified forms are shown in the accompanying drawings, in which Figure 1 shows the position of the straight pieces or stakes and the movable gripping teeth or springs which catch and hold them. Figs. 2,3, and 4 are side, front, and top views of a machine for making fiat basket-bottoms. Figs. 5 and 6 are side and front views of a machine for making hampers, rectangular in plan.

Upon a fixed rail or frame 1 and a movable one 2 gripping-teeth 3 to 8 or springs 9 to 12 and gripping-teeth 13 to 18 or springs 19 to 22, respectively, are fixed. In Fig. 1 two forms of gripping devices are shown, those at the left being termed gripping-teeth and those at the right g1'ipping-springs, and either form may be employed. The stakes 23 are held by means of the gripping-teeth 3 to 8 and the springs 9 to 12 upon the fixed rail 1, the force of the springs being so proportioned that the stakes can be drawn away from them by the gripping-teeth 13 to 18 and the springs 19 to 22 if, in the first place, the movable rail 2 is moved to and from the fixed rail 1, and, secondly, the gripping-teeth 13 to 18 and the springs 19 to 22 are opened by an arrangement described later on as soon as they are brought in contact with the stakes which are in the gripping-teeth 3 8 and the springs 9 12.

In the position shown in Fig. 1 the teeth 13 16 17, as well as the springs 20 and 21 on the movable rail 2, are closed and have taken thestakes 23 from the corresponding gripping-teeth 3 6 7 and the springs 11 on the fixed rail 1, so that now only the teeth 4:, 5;

and8 and the springs 9 and 12 on the fixed rail 1 retain their stakes. The shed or place for the cross-withes to be inserted in is therefore now formed by the stakes in 13, 16, 17, 20, and 21 on the one side and in 4: 5 8 9 12 on the other side. The regulation of the ac tion of the gripping-teeth and of the springs on the loose rail 2 is effected in the following way: In bearings on the rail 2 the axle'24 revolves, on which cams or projections 25 are arranged. One end of the axle 24 carries a four-toothed wheel 26, which in the lowest position of the rail 2 is turned partly round or automatically turns itself, (see below,) so that as the cams25 are arranged upon the axle 24 in a position corresponding with the desired movements of the stakes to leave the space or shed forthe cross-withes at each further quarter-revolution of the axle corresponding stakes 23 are drawn out from the gripping-teeth 3-to 8 and the springs 9 to 12. In the position shownin Fig. 1 the grippingteeth 13 16 17 and the springs 21 are opened by the cams at the moment when they have moved above the stake 23 in the grippinge teeth 3 6 7 and the springs 10 11 on the fixed I i a rail 1, so that when the rail 2 goes up again l the lever 58 is driven up and operated. The

the stakes 23, taken by 13 16 17 21, overcome the force of the springs of the gripping-teeth 3 6 7 and of the springs 11, and follow the movement of the rail 2.

The construction of the gripping-teeth and of the springs can be varied as desired, and modified forms of teeth and springs may be substituted for them.

The use of the above-described arrangement for the preparation of fiat bottoms for baskets is shown, by way of example, in Figs. 2 to t.

On the frame 27 the axle 29 turns in bearings 28 and driven by the belt-pulley 30 by means of the toothed wheels 31, 32, and By a coupling 34 and a foot-lever 35 the machine can be thrown in and out of gear. The driving-shaft 36, (with the pulley 30, the toothed wheel 31, and the coupling 34,) drives, by means of the toothed wheels 37, the crankdisk 38, which by means of the connectingrod. 39 drives the beatingbar 40 backward and forward on the bars 1 of the frame 27. The beater LO serves to drive the weft material or withes into the space or shed prepared for it between the stakes 23. On the bars 41 also slides a clamping arrangement 4:2, which firmly holds one end of the stakes 23 and which also allows the finished wicker-work to move forward by degrees on the bars &1 toward the back of the machine. For this purpose the chain as is attached to the clamping device 42 and is led over the rollers and the roller or chain-wheel 15, which are carried by the frame 27. The roller 15 carries on one side one part 46, Fig. 4, of a brake or friction coupling, the other adjoining part of which, a7, is movable end wise upon the squared part of a rod 48, fixed to the frame 27, and is pressed out by a spring 4:9. The pressure caused by the spring 49 between the two parts 46 and 47 serves for regulating the tightness or looseness of the wicker-work, as the greater the pressure between the two parts 46 and a? the greater is the resistance to the backward movement of the clamp &2 on the bars 41 and to the action of the beater-bar, and consequently the wickerwork is the more closely formed. If the brake is released by shifting the movable member t7 away from the member &6 in the usual way, the chain-wheel &5 can be turned back and the clamp 42 returned to its original position in the front part of the machine, when fresh stakes can be inserted and clamped for the recommencenient of work. For this purpose the axle 50 of the gear-wheel 50 is provided with a square end 51 (see Fig. 2) to receive a handle (not shown) by which said shaft may be rotated.

Above the axle 29 a spindle 55 turns in bearings 5 and carries arms 56, to the outer end of which is fixed the rail 2, which by means of the eccentric 57 on the spindle 29 and rail 2 carries the gripping-teeth 59, which correspond with those 13 to 18 and the springclips 19 to 22 in Fig. 1. On the rail 1, fixed to the frame 27, are carried the grippingteeth 60, corresponding with those 3 to8 and the springs 9 to 12 in Fig. 1.

The shifting of the axle 24: with the cams 25 for adjusting the position of the teeth 59 on the movable rail 2 is effected by the carrier-arm 61, which carries the ratchet-pawl 62, gearing with the ratchet-wheel 26, and rests upon the projection 63 on the rail 2. This arm 61 at the downstroke of the arms 56 strikes the stop 6 L on the rail 1, so that the ratchet-wheel takes the position shown in dotted lines in Fig. 2. At every downstroke of the rail 2 the axle 24. is turned through ninety degrees, so that the stakes which were raised are brought down and those which were down are taken up, and by the continuous changes the positions requisite to form the shed to receive the withe of the wickerwork are insured.

The machine shown in Figs. 5 and 6 consists of the following arrangement for making the rectangular baskets. On the frame 65 slides "on the bar 66 a vertical plate 67, which is provided with an arrai'igement for carrying a second plate 68, which holds the basketbottom and the wickerwork. The plate 68 has upon one side a cylindrical projection 69 and a rectangular plate 70, having its corners rounded, Fig. 6, while a second rectangular plate, 71, is fixed upon the pin or stud 69, which can move vertically in the slit or opening 73 in the plate 67 and its projection 72, so that the middle of the basket may be brought to different heights, and the upper row of stakes, on which the process for making the wickerwork by interlacing withes takes place, can always be adjusted at the same height. The size and shape of the rectangle is therefore determined in proportion to the size and shape of the basket to be made. Against the rectangular plates 70 and 71 a plate 7% presses, the spindle of which passes through the plate 67 and its projection 72 and is pressed up by the spring 75, while by pressure on the foot-pedal 76 the pressure of the spring is overcome and the plate 74 is withdrawn from the rectangular plates 70 and 71, and the plate 68, together with the wickerwork upon it, can be turned round, so that another side of the basket can be worked on. On the rail or frame 1, which is firmly connected with the plate 68 by the rods 77 passing back through the bottom of the basket, are arranged according to the shape of the basket springs (or gripping-teeth) 78, which correspond with the gripping-teeth 3 to S and the springs 9 to 12 of Fig. 1, while the spring 79 on the rail 2 takes the place of the gripping-teeth 13 to 18 and the springs 19 to 22 of Fig. 1. In Figs. 5 and 6 the separate springs are for clearness omitted. The ends of the chains 94: are attached to the plate 67, and the chains pass over the rollers or wheels 95 and 96,0f which those 95 are provided with braking devices exactly in the same way and for the same purpose as in the case of those 45 already described, Figs. 2 to 1. The rail 2 is carried at the end of arms 80, which can oscillate round the short spindle 81 or the bolt 82 in the frame by the action of the eccentric 83, fixed on the shaft 84. The eccentric 83 is pressed against the arm 85, carrying weight 86 for balancing the movable frame 2 at the ends of the arms and placed at right angles to the arms which carry the latter arms 80. The adjustment of the spindle 2 1, which carries the cams 25, is also in this case effected by a ratchet-Wheel 26, Fig. 5, the pawl of which, 62, strikes with its end 61 against the stop 64 on the frame 65 when the arms 80 and the rail 2 go down. The arms 80 are so formed that they act as guides for the beater 87, by which the wickerwork is pressed together, and which is operated by' means of the connecting-rod 88, driven by the crank-disk 89 upon the end of the shaft 81. The working of both shafts 81 and 84: is effected from the shaft by means of toothed gears 91, and the machine is thrown into gear when desired by the pedal-lever 92 operating the coupling 93 and remains in gear as long as the pressure on the lever continues.
